QTR-Quadtone RIP

Sorry guys but now I can't post replies with any of the "reply" buttons. I cannot believe what Yahoo have gone and done with Yahoo Groups, they've completely messed it up.

First of all thanks for your inputs.

I checked out that print group and the owner appears rather stringent about only users of PDN being members. If my quest for the perfect inkjet negative fails I'll shoot him an email. There are inks (black) dedicated to making film positives. One such brand is "Black Max". They are supposed to be very fast drying. My idea is to centrifuge the original ink out of the cartridges then fill all cartridges with this ink, block the outlet holes then centrifuge again to get all the air bubbles out. I've done the latter numerous times when refilling cartridges, works great. For now though I'm just playing with finding the best control of depositing max ink.

Having viewed many screenprinting threads, they always talk about achieving the max deposition of ink to get the opacity on their film positives.

I had a quick read of the calibration PDF and if I've got it correct it seems you can just about make QTR flood the print material. That sounds like what I need LOL.

Regarding the print material absorbing the ink, many people have talked about the quality of the film positive material. Seems the high quality transparencies which are specifically designed for this purpose take the ink much better and dry very fast, whereas a general cheapy inkjet transparency can give comparatively atrocious results.

I'm wondering now if QTR can just "fire" the black cartridge, so I don't have to fill all cartridges with the black screenprinting ink.

Thanks guys,

Keith.

Yes, you can flood the 'paper' (you can even flood real paper), and you 
can use just one cartridge. just disable the others (I think). Its a 
long time since I tried making digital negatives.
